B Series Intake Manifold

Skunk2 Racing’s Pro-Series Intake Manifold improves airflow thus increasing horsepower by as much as 8% over stock manifolds on stock engines and even more on modified or forced-induction engines. Skunk2 manifolds significantly increase horsepower between 3000-8800 rpm; the broadest powerband increase in the industry. Our new Pro-Series design features a 22% increase in power over our previous design. Engineered with a larger plenum and tapered runners, Skunk2 manifolds increase and accelerate airflow, and are designed to increase the effects of wave scavenging at the engine’s optimum operating RPM range providing a broad overall increase in usable power. Each runner entry is also modified to balance airflow between cylinders. Oversized throttle bodies can be used as a result of the modified IAC opening on the flange. Like OEM factory manifolds, Skunk2 manifolds are shell molded and CNC machined, to achieve superior strength, high-quality finish, and a precise fit. Each manifold is vacuum tested to ensure quality and leakfree operation. The Skunk2 Pro-Series manifold utilizes all stock sensors and auxiliaries for a simple bolt-on installation that delivers maximum power. Ideal for NA and Forced Induction

Composite Intake Manifold

Skunk2 introduces its new series of composite intake manifolds and fuel rails. Skunk2’s new composite components are made using a proprietary casting process, from a carbon reinforced aerospace thermo-polymer composite that is 33% lighter, 60% stronger, and runs up to 100ºF cooler than aluminum. Keeping the air and fuel cooler results in a significant increase in horsepower and torque. This composite is also chemical resistant to all types of fuels including alcohol.

• Up To 3% HP Gain Just By Keeping Fuel Cooler
• -8 AN End Threads With 0.625” Internal Bore
• Can Support Up To 1200 HP
• Can Be Used With Stock Fuel System
• Chemical Resistant To All Fuels Including Alcohol

Composite Fuel Rail

Skunk2 introduces its new series of composite intake manifolds and fuel rails. Skunk2’s new composite components are made using a proprietary casting process, from a carbon reinforced aerospace thermo-polymer composite that is 33% lighter, 60% stronger, and runs up to 100ºF cooler than aluminum. Keeping the air and fuel cooler results in a significant increase in horsepower and torque. This composite is also chemical resistant to all types of fuels including alcohol.

Skunk2’s new cutting-edge composite fuel rails are made using our proprietary carbon impregnated aerospace thermo-polymer composite. This material insulates the fuel from both radiant and conductive heat transfer under the hood. Keeping the fuel cooler results in an increase in horsepower and torque. We have seen power gains of up to 3% in real world testing. Skunk2 composite fuel rails feature a large 0.625” internal bore with radius inlets to the injectors thus improving flow characteristics. This type of radius injector inlet design is not possible with extruded and drilled aluminum fuel rails (which have sharp angles internally where the main bore meets the injector bores). Skunk2 fuel rails can be used with factory fuel lines and fuel regulators.

Cutting Edge
• Up to 3% Gain Just by Keeping Fuel Cooler
• -8 AN End Threads with 0.625" Internal Bore
• Can Support Up to 1200HP
• Can Be Used with Stock Fuel System
• Chemical Resistant to All Fuels including Alcohol

Large 0.625" internal bores help dampen injector pulsations and can support up to 1200hp. Radiused injector inlets for maximum fuel flow. Smooth interior finish and radiused injector outlets are not possible with extruded and machined aluminum fuel rails.
